Change the data set of Table 16.1 by adding a value of the vapor pressure at 70

Question:

Change the data set of Table 16.1 by adding a value of the vapor pressure at 70^—¦C of 421 torr ± 40 torr. Find the least-squares line using both the unweighted and weighted procedures.

Table 16.1

I (K) t (°C) Vapor pressure Expected error (Torr) (Torr) 25.00 298.15 55.9 3.0 3.0 30.00 303.15 70.0 308.15 93.8 4.2 35
